水泥回转窑筒体表面余热回收供暖系统的设计

Design of a Heating System Utilizing Waste Heat Recovery from Cement Rotary Kiln Surface

介绍了山东某水泥厂2 500t/d回转窑筒体表面辐射热回收供暖系统。根据供暖系统负荷,计算了所需的回转窑辐射热的取热量,设计了供暖系统的取热装置、热量存储和输送系统以及控制系统。按窑实际年运转300d计算,可以从窑筒体提取热量136 800 0kWh,大约相当于168 000kg标准煤,实现了节能减排和资源综合利用的目的。

This paper introduces a radiant heat recovery heating system that the heat is obtained from a 2 500 t/d cement rotary kiln in Shandong Province. According to the load of heating system, the author calculated the amount of heat required from the surface of rotary kiln, and designed the heating device, heat storage and transportation system and control system of heating system. According to the actual operation of cement kiln for 300 days a year, 1 368 000 kWh of heat can be obtained from the surface of rotary kiln, which is approximately equal to 168 000 kg of standard coal. The system achieves the goal of energy saving, emission reduction and comprehensive utilization of resources.
